摘要
现在信息检索的应用已经越来越广泛，但要在具体领域中做到准确搜索，仍然是一件比较难的事情。该文提出一种基于概念语义树的语义相似度计算方法，综合考虑了概念的语义关系、层次结构和继承关系等因素，尽可能的地提高在特定领域中的信息检索效率，并最后通过实验，验证了该方法的可行性。
At present, the application of information retrieval has been widely used, but it is still a difficult thing to be accurate in the spe- cific field of searching. This paper provides a semantic similariW calculation method based on the concept semantic tree, considering the concept of the semantic relations, hierarchies, and inheritance and other factors, as much as possible to improve retrieval efficiency in specif- ic areas of information, and at final, demonstrate the feasibility of the method by experiment.
